Abstract: A battery has a housing (4) with battery cells (5) that are temperature-controlled/cooled by a liquid temperature control/liquid cooling system (10) and a gas temperature control/gas cooling system (15). The gas temperature control/gas cooling system (15) has at least one closed circuit (16) in the housing (4).

Abstract: A section of roadway has at least one integrated induction loop designed to inductively charge a vehicle battery of a hybrid or electric vehicle that is situated on the induction loop. The section of roadway is arranged in the region of a road in which the traffic is at least temporarily stationary. As a result, useless time waiting at traffic lights or railway crossing gates can be used productively.

Abstract: An electrical energy store of a motor vehicle, in particular a high voltage energy store of a hybrid vehicle or of an electric vehicle, having a housing (11) and having storage modules (12) accommodated in the housing (11). The housing (11) having a supporting element (17) connecting the electrical energy store to a vehicle bodywork structure of a motor vehicle. The temperature of the storage modules (12) can be controlled via the supporting element (17).

Abstract: A flow energy installation, in particular a wind power installation, having a housing which has a droplet-shaped cross section and can be adjusted about its vertical axis aligned with the flow direction, in particular the wind direction, wherein the housing has an inlet opening on the front face to an inner flow channel, which leads to at least one outlet opening which is arranged in particular at the side on the housing, and at least one axial incident-flow propeller is arranged in the flow channel, wherein the flow channel has boundary surfaces which run in a convex shape, in its inlet area adjacent to the inlet opening.
